Description

{CERAMIC HEATING DEVICE COMPRISING NATURAL BINDING MATERIALS}

The present invention relates to a ceramic heating device including a natural adhesive, and more particularly, to a ceramic heating device using a natural adhesive, which is lightweight, durable, and has excellent thermal conductivity.

Generally, a heat generating substrate has a structure in which a non-conductive substrate is coated with a heat generating material having electrical conductivity and electrodes are disposed thereon. If a direct current or an alternating voltage is applied to both ends of the electrode, electric current flows through the electrically conductive heating material to generate heat.

The amount of heat generated from the electrically conductive heating material is limited by the electrical resistance of the electrically conductive heating material. Limiting the amount of heat generated by the electrical resistance in a heat generating device that requires a larger amount of heat can be a decisive problem.

Perlite (perlite) is an obsidian formed when rapid volcanic rock is cooled. The water contained therein evaporates and swells when heated to a high temperature. It becomes a fine porous white mineral, has a neutral acidity, has little nutrient content, Seeds, pathogens and pests do not live at all.

The pollution-free pearlite and vermiculite are three-layer structured, orbital minerals, which contain moisture between the layers. When heated, dehydration takes place between the layers, which expands and exfoliates, thus serving as a porous insulation insulation mineral.

The pearlite (perlite) used in the present invention may have a test report as shown in Table 7 below.

The ceramic clay used in the present invention may be bentonite. Such a ceramic clay may have swellability. In other words, when ceramic clay reacts with water, calcium-based bentonite expands to about 3 times, sodium bentonite expands to about 15 times, and can absorb water up to 5 times its weight. The expanded ceramic clay is gelled and the gel may have the property of rejecting water. Using these properties, it can be used as a raw material for waterproofing materials.

In addition, ceramic clay has the property of mixing with other materials to cause other materials to stick to each other. The ceramic clay is not chemically active and does not affect the original chemical properties of the adhesive material. At high temperatures this property remains unchanged and can be widely used as an adhesive for sand casting.

In addition, the ceramic clay forms a gel, so other materials with low viscosity can be concentrated. In this case, the suspension using the ceramic clay can be used as an additive for various industrial raw materials such as paint chemicals, graphite, etc., since it forms a perfect colloid state without precipitation even after a long time.

The ceramic clay used in the present invention may have a test report as shown in Table 8 below.

[Example]

Vermiculite, pearlite and ceramic clay are crushed by a crusher. That is, the second steel sheet can be formed by crushing vermiculite, pearlite, and ceramic clay finely with a size of 0.1 mm-1 mm and processing into a powder form.

Next, the first steel sheet can be formed by mixing the vermiculite, the pearlite and the ceramic clay powder with at least one mineral selected from the group consisting of sericite, sepiolite, zeolite, kaolin, loess and feldspar and a natural adhesive.

Next, the heat-generating net 230 is inserted into the first steel plate and the second steel plate, the mixture is injected into the mold, and the mixture is shaped to fit the shape of various heat-generating devices. The product injected into the mold is dried by natural drying or drying through a dryer to produce a ceramic heating device.

The ceramic heater and the method of manufacturing the same according to the embodiment of the present invention use lightweight materials by using natural materials, so that they can be easily handled after molding, thereby improving work efficiency.

In addition, the ceramic heating device and the manufacturing method thereof according to the embodiment of the present invention can provide a beneficial environment to the human body by adding loess, and minimize the cause of environmental pollution.

The ceramic heating apparatus 200 according to the present invention is characterized in that at least one mineral selected from the group consisting of vermiculite, pearlite and ceramic clay having a particle size of 0.1 mm-1 mm is rapidly heated at 800-1200 and expanded to a size of 6-10 times step; Mixing at least one mineral selected from the group consisting of sericite, sepiolite, zeolite, kaolin, loess and feldspar and a natural adhesive as described above; Interposing an exothermic net; And a step of heating and pressure molding.

Vermiculite, pearlite and ceramic clay in the form of powder having a particle size of 0.1 mm-1 mm are mixed with a natural adhesive and easily mixed when agitated, so that the agitated product is more easily cured. As a result, the ceramic heater can be very rigid and the surface can be smooth.

One or more minerals selected from the group consisting of vermiculite, pearlite and ceramic clay are rapidly heated at 800-1200 and expanded to a size of 6-10 times, and then they are expanded in the group consisting of sericite, sepiolite, zeolite, kaolin, A natural adhesive such as the one described above and a natural adhesive agent as described above are mixed and press-molded while being inserted into the mold and heated to form at least one mineral selected from the group consisting of sericite, sepiolite, zeolite, kaolin, As the adhesive is sandwiched between the expanded mineral particles, the natural adhesive enhances the adhesion between the mineral particles to enhance the strength.

Also, since the surfaces of the pores opened by the expanded mineral are blocked by the natural adhesive, they are bonded to each other, so that the minerals contained in the molded product have a closed pore shape, so that the sound insulation effect and the heat insulation effect are excellent. In particular, since the mineral powder has excellent far-infrared radiation efficiency and emits far-infrared rays, it exhibits excellent performance as a decorative plate for an interior.

Further, the first thermal conductivity may have a higher thermal conductivity than the second thermal conductivity. The second thermal conductivity of the first steel strip 210 and the second thermal conductivity of the second steel strip 220 are different from each other, so that they can be applied to different environments or situations.

That is, if the thermal conductivity is high, the surrounding can be warmed quickly, and if the thermal conductivity is low, the temperature is gradually warmed, but the warmth can be maintained for a long time or the heat conduction can be blocked. At this time, the first steel plate 210 having a relatively high thermal conductivity is disposed on the surface where heat is radiated, and the second steel plate 220 having a relatively low thermal conductivity is disposed on the opposite surface, So that the heat efficiency of the heat generating device can be improved.

The heat generating net 230 is disposed between the first steel plate 210 and the second steel plate 220 and transmits heat generated in the first steel plate 210 and the second steel plate 220. The heat generating net portion is substantially the same as the heat generating net portion 230 according to the first embodiment described with reference to FIGS. 1 to 3, and will not be described here.

In addition, it may include a natural adhesive 240 that is laminated between the first steel sheet 210 and the second steel sheet 220 to fix the heating net 230. The natural adhesive 240 is substantially the same as the adhesive 240 of the natural material according to the first embodiment described with reference to FIGS. 1 to 3, and will not be described here.

Although the present invention has been described with reference to the embodiment thereof, the present invention is not limited thereto, and various modifications and applications are possible. In other words, those skilled in the art can easily understand that many variations are possible without departing from the gist of the present invention.
